 Amlaíb Cuarán of Dublin, King of Northumbria and Dublin 1)Died 980 Iona, Argyll, Scotland Notes: Amlaíb mac Sitric (c. 927 - 980; Old Norse: Óláfr Sigtryggsson), commonly called Amlaíb Cuarán, in Old Norse: Óláfr kváran, was a 10th-century Norse-Gael who was King of Northumbria and Dublin. His byname, cuarán, is usually translated as "sandal". His name appears in a variety of anglicized forms, including Olaf Cuaran and Olaf Sihtricson, particularly in relation to his short-lived rule in York. He was the last of the Uí Ímair to play a major part in the politics of the British Isles. Amlaíb was twice, perhaps three times, ruler of Northumbria and twice ruler of Dublin and its dependencies. His reign over these territories spanned some forty years. He was a renowned warrior and a ruthless pillager of churches, but ended his days in retirement at Iona Abbey. Born when the Uí Ímair ruled over large areas of the British Isles, by his death the kingdom of Dublin was a minor power in Irish politics. At the same time, Dublin became a major centre of trade in Atlantic Europe and mastery over the city and its wealth became the supreme prize for ambitious Irish kings.

Sitric mac Amlaíb of Dublin 1)Born ± 970 Died 1042, approximately 72 years Notes: Sigtrygg II Silkbeard Olafsson (also Sihtric, Sitric and Sitrick in Irish texts; or Sigtryg and Sigtryggr in Scandinavian texts) was a Hiberno-Norse king of Dublin (possibly AD 989-994; restored or began 995-1000; restored 1000 and abdicated 1036) of the Uí Ímair dynasty. He was caught up in the abortive Leinster revolt of 999-1000, after which he was forced to submit to the King of Munster, Brian Boru. His family also conducted a double marriage alliance with Boru, although he later realigned himself with the main leaders of the Leinster revolt of 1012-1014. He has a prominent role in the 12th-century Irish Cogadh Gaedhil re Gallaibh and the 13th century Icelandic Njal's Saga, as the main Norse leader at the Battle of Clontarf in 1014. | |||
